C# 由于在大型列表中的位置而导致EF超时异常。Contains（）

当我向以LINQ样式编写的查询添加条件筛选器（或

WHERE

）时，我遇到了一个异常

我得到一个例外：

问题过滤器：

if (filterCriteria.ContainsKey(isExcludeKiosk) && filterCriteria.TryGetValue(isExcludeKiosk, out var actualExcludeKiosk))
{
    if ((bool)actualExcludeKiosk)
    {
        var kioskRecordsList = await context.View_BillInfoDetailWithKiosks.Where(w => w.KioskMadeId != null).Select(s => s.KioskMadeId ?? -1).ToListAsync();

        result = result.Where(where => !kioskRecordsList.Contains(where.REFERENCE_ID));
    }
}

此文件管理器将取出由

信息亭生成的某些
账单详细信息
。没有直接关系。我在数据库中生成了一个视图，该视图使用一个SQL链接服务器生成一个可能的ID列表，这些ID由
kiosk
生成。问题是名单上大约有12000条记录，
账单明细也超过500000条。我这样做是为了得到一个SQL查询EF executes的转储，该查询在Management Studio中执行大约需要十分钟：

我执行了一个执行计划，注意到最后一个排序占了80%，所以我删除了它。我把时间缩短到1.11分钟。但这还需要一段时间

计划：

还有优化的余地吗？
@Hassan，
首先，您不应该从数据库中将Kiosk列表提取到内存中，然后将其传递给linq查询。这会导致查询未优化。
尝试以使所有命令都能在数据库中运行的方式编写查询。
这样，您将使用一个将已存在的linq查询，而不是IN运算符

var conditionSubQuery=context.View_BillInfoDetailWithKiosks.Where(w => w.KioskMadeId != null);
result = await result.Where(r => !conditionSubQuery.Any(c=>r.REFERENCE_ID==c.KioskMadeId)).ToListAsync();

问候,，
Massoud
您的数据库是否有索引？如果是，它们是碎片化的吗？只是通过避免内存转储，查询执行下降到24秒。@哈桑，在优化LINQ查询之后，您应该考虑通过任何合适的索引优化表以使查询运行得更快。一旦主要瓶颈消失，执行计划开始给出索引建议，我看到了所有这些建议。现在是1.11秒。
